More Data Captain!
 
 
Now for my mystery of the day. Was doing more tests on coil / alternator cooling & wingtip testing today and got around to stall tests.  I was pleasantly surprised to find that my clean stall speed was down a full 5 MPH.  That is HUGE,  especially from such a simple mod.   Repeated the test multiple times, accelerated, power on, idle, 1 mph/ 10 second deceleration, the works.  The change was real.   Then I tested 1/2 & full flap stall expecting that I would see the usual 4-5 mph drop in stall speed.  Absolutely no difference.  Stall was the same clean or dirty.
 
Anyone care to take a stab at this?

How about more data Capt Tracy??
 
You said you sharpened the leading edge of tip but I never saw anything more. How about a picture?  Sounds too good to be true, but trust you to wring it out. Is the GPS agreeing with the airspeeds. You might be effecting the pitot input!
